The DG1411 are ± 15 V precision monolithic quad single-pole single-throw (SPST) CMOS analog switches. Built on a new CMOS process, the Vishay Siliconix DG1411 offer low on-resistance of 1.5 O. The low and flat resistance over the full signal range ensures excellent linearity and low signal distortion. The new CMOS platform provides low power dissipation, minimized parasitic capacitance, and low charge injection.The devices operate from either a single 4.5 V to 24 V power supply, or from dual ± 4.5 V to ± 15 V power supplies. The analog switches don"t require a VL logic supply, while all digital inputs have 0.8 V and 2 V logic thresholds to ensure low-voltage TTL / CMOS compatibility.The DG1411 are bi-directional and support analog signals up to the supply voltage when on, and block them when off. The devices each feature four independently selectable SPST switches.
